                    NFS version 4.0 Trunking Update
                draft-ietf-nfsv4-mv0-trunking-update-05

Abstract

   The file system location-related attribute in NFS version 4.0,
   fs_locations, informs clients about alternate locations of file
   systems.  An NFS version 4.0 client can use this information to
   handle migration and replication of server filesystems.  This
   document describes how an NFS version 4.0 client can additionally use
   this information to discover an NFS version 4.0 server's trunking
   capabilities.  This document updates RFC 7530.
